## About

I am an Electric Vehicle \(EV\) professional with 7\+ years of hands\-on experience in vehicle integration, product testing & validation, and fleet operations, bringing together both technical depth in R&D and operational leadership\. My expertise spans the full EV lifecycle \- from new technology development and validation testing to service, maintenance, and optimization of large EV fleets\. Core Strengths\- R&D and Product Testing \(Batteries, Vehicle\): In\-house validation and development testing of Metal\-Air batteries at Testing agencies\. Performance and certification testing of Lithium\-Ion batteries as per AIS 039 & AIS 040, including cycle life, abuse testing, and compliance evaluation\. Vehicle Integration & Testing: Validation of 2W/3W vehicles and EV retrofits as per KPIs and global standards, including chargers, controllers, DC\-DC converters, and IoT systems\. Battery Systems: Integration and testing of Li\-ion and Metal\-Air chemistries across swapping & non\-swapping applications; hands\-on with in\-house pre\-certification, test protocols, and AIS 156 validation\. Homologation & Certification: Direct experience with Type Approval, COP, and certification testing with ICAT/ARAI and global private testing organizations\. Technology & Analytics: Leveraging IoT and data analytics for vehicle performance monitoring, predictive maintenance, and root cause analysis in battery/vehicle testing\. Fleet & Service Operations: Proven expertise in EV fleet optimization, technical service operations, inventory planning, and vendor evaluation with a focus on reducing OPEX\. Leadership & Partnerships: Managing cross\-functional technical teams, collaborating with OEMs, suppliers, and charging ecosystem partners to ensure technical reliability and cost optimization\. What I Deliver\- Reliable battery testing & validation frameworks for advanced chemistries \(Li\-ion & Metal\-Air\)\. Improved EV fleet uptime and reliability through process optimization & predictive maintenance\. Cost\-efficient procurement and inventory planning, reducing OPEX in EV ops\. End\-to\-end support for technology integration projects \- batteries, chargers, controllers, motors, DC\-DC converters, and IoT systems\. Proven results in vehicle performance testing, development validation, and model\-based testing\. With a strong foundation in R&D, product validation, and operational execution, I help organizations scale EV adoption with reliability, compliance, and efficiency\. My focus areas include EV Testing & Validation, Battery Systems, R&D in advanced energy storage, and Program/Project Management\.
